一、产品特点：夹套保温截止阀按结构分为BJ41W夹套保温直通式截止阀和BJ45W夹套保温直流式截止阀，主要用于石油，化工，冶金，制药等各类系统中，以输送常温下会凝固的高粘度介质。该系统阀门的夹套焊装于阀门的两法兰之间，阀门的侧面，底部设置由夹套的连接口。由于增加了夹套，此种阀门的连接法兰尺寸要比同一规格普通截止阀的连接法兰大一到两个规格，但结构长度与同规格的阀门相同，夹套中可自由地流过蒸汽或其它热的保温介质，确保粘稠介质可以顺畅地流过阀门。二、主要技术参数：型号公称压力PN（MPa）试验压力适用温度适用介质保温套压力（MPa）壳体密封BJ41W-16P、R、C1.62.41.8≤350硝酸类≤1.0BJ41W-25P、R、C2.53.82.8≤350硝酸类≤1.0三、主要外形连接尺寸：型号公称通径DNmm尺寸LDD1D2B-fZ-ΦdHDo2-GWPBJ41-16RHC1513095654516-24-141701703/820150105755516-24-141901903/825160115856516-24-142052053/8321801351007818-24-182702701/2402001451108518-34-183103101/25023016012510018-34-183583581/26529018014512018-34-183733731/28031019516013520-38-184354351/210035021518015520-38-185005001/212540024521018522-38-186146141/215048028024021024-38-236746741/220060033529526426-312-238188181/225073040535532030-312-259499691/2型号公称通径DNmm尺寸LDD1D2B-fZ-ΦdHDo2-GWPBJ41-25RHC1513095654516-24-142331203/820150105755516-24-142751403/825160115856516-24-142851603/8321801351007818-24-183021801/2402001451108518-34-183552001/25023016012510020-34-183622401/26529018014512022-38-184002801/28031019516013522-38-184303201/210035023019016024-38-184653601/212540027022018828-38-235504001/215048030025021830-38-257004001/220060036031027834-312-257804501/225073042537033536-312-309005501/2型号公称通径DNmm尺寸LDD1D2D6B-fZ-ΦdH2-GWPBJ41-40RHC151309565454016-24-142333/82015010575555116-24-142753/82516011585655816-24-142853/832180135100786618-24-183021/240200145110857618-34-183551/2502301601251008820-34-183701/26529018014512011022-38-184081/28031019516013512122-38-184361/210035023019016015024-38-234751/212540027022018817628-38-255581/215048030025021820430-38-257201/220060037532028226038-312-308001/2型号公称通径DNmm尺寸LDD1D2D6B-fZ-ΦdH2-GWPBJ41-64RHC1517010575555518-24-142403/82019012590686820-24-142803/825210135100787822-24-142903/832230150110828224-24-183251/240260165125959524-34-183601/25030017513510510526-34-184101/26534020016013013028-38-184301/28038021017014014030-38-184651/210043025020016816832-38-185371/212550029524020220236-38-236301/215055034028024024038-38-257901/220065040534530030044-312-259101/2)
